15 31/40 to the nearest whole number

Dahasolnce [82]

Answer:

Step-by-step explanation:

Because the number is closer to 16, it can be rounded off to that. 15 31/40 is the same as 15.78. When the decimal is over .50 it is rounded up to the next whole number, but when it is under .50 it si rounded down to the nearest whole number. ex. since this one is over the .50, it's rounded up, but if it were 15.36 then it would be rounded down to 15. hope this helps :D

Find the values of s1 and r for a geometric sequence with s4 = 18 and s6= 8<br>

stiv31 [10]

Answer:

see below

Step-by-step explanation:

The ratio of terms that are two terms apart (s4 and s6) is the square of the common ratio:

s6/s4 = r^2

r = √(8/18)

r = 2/3 . . . . . matches choices A and C

Using the formula for the general term, we now know enough to find the first term:

sn = s1·r^(n-1)

s4 = s1·(2/3)^(4-1)

Using s4 = 18 and multiplying by (2/3)^-3, we get ...

18·(2/3)^-3 = s1 = 18·27/8

s1 = 243/4 . . . . . matches choice A
